Filed: 1937-05-21
Abstract: 495,799. Variable resistances. STANDARD TELEPHONES & CABLES, Ltd., and HELLIER, W. H. M. May 21, 1937, No. 14179. [Class 37] A variable resistance in which a contact member is movable over a resistance wire is arranged so that the displacement of the slider is a logarithmic function of the resistance between one terminal and the slider by making the resistance wire of contiguous lengths having different resistances per unit length, e.g. by forming them of different materials or different gauges. In the construction shown, two cylindrical formers 1, 2 are disposed between end plates 3, 4 in which is mounted a screwed rod 5 passing through a nut 6, which carries flat resilient wipers 7, 8 having contact studs 9. One or both ends of the rod 5 are slotted for insertion of a screwdriver. Each of the windings on the formers 1, 2 consists of successive lengths of wire having such resistances per unit length that an approximately logarithmic relation exists between the displacement of the slider 6 and the resistance between this and one end of the former. In an example each winding on the formers 1, 2 consists of four successive lengths of wire, the first and second consisting of constantan wire of 37 and 40 S.W.G. respectively, and the third and fourth of wire of the material known under the Registered Trade Mark " Nichrome," of 40 and 43 S.W.G. respectively. The first and third sections are enamelled, the others being double silk covered, the increased thickness of insulating-material compensating for the decreased gauge of wire and thereby enabling the slider to pass smoothly from one section to another.

Filed: 1965-04-05
Abstract: 1,106,204. Programmed machine tool control. ING. C. OLIVETTI & CO. S.p.A. April 5, 1965 [April 7, 1964], No.14440/65. Heading G3N. A digitally programmed control system, as disclosed in Specification 1,090,238, is modified so that it can be used with a workpiece clamped in any position on the work-table by initial adjustment with respect to a reference member. As shown, programmed position orders are fed through a common digital to analogue converter D/A to position measuring transformers IX, IY, IZ having members SSX, SSY, SSZ movable with the work-table and members RSX, RSY, RSZ which are displaceable, by manual, or servodriven, wheels MX, MY, MZ, with respect to. the fixed portion of the machine-tool. Signals induced in windings 8, representative of position errors of the work-table, are fed to servosystems positioning the work-table through motors SMX, SMY, SMZ. For initial positioning, the converter D/A is fed from a fictitious address generator 39 whereby the motors SMX, SMY, SMZ are cyclically fed with signals simulating a zero position order to bring the work-table to the zero position of the reference member within the pitch of the position measuring transformer. During a second phase, the operator positions the work-table along one axis at a time, the other axis being maintained in position by the zero position orders. Considering the Y axis, a push-button is depressed to generate a signal AMY controlling a switch 4OY so that the Y axis servosystem is interrupted and the control of motor SMY transferred to a potentiometric coarse positioning device QY. In a third phase, the switch 4OY is returned to normal and the motor SMY controlled by the cyclic zero position order. In a final phase, the handwheel MY is rotated and the reference member adjusted to coincidence with a reference point on the fixed position of the machine, the reference member and work-table being maintained in correspondence by the cyclical zero position orders.

Abstract: 573,220. Variable-speed gearing. DERUNGS, E. A. Sept. 3, 1943, No. 14443. Convention date, Oct. 9, 1942. [Class 80 (ii)] Preselector control mechanism for variablespeed gearing comprises gear-changing levers 64, 65, 66, pivoted on an axle 62 and engaging gear-shifting forks 76, each lever having pins 29, 30, coacting with slots 27, 28 in cam plates 17. The latter are pivoted on a pin 41 in a block 11 which can be moved in one direction by a cable 9 under the action of an electromagnet 7, 8, and in the opposite direction by springs 33. A fixed base 6 carrying the electromagnet 7, 8 and spring supports 34 has pairs-of electromagnets 69, 70, the armatures 67, 68 of which have pushers 20 projecting towards the member 11. The slots 27, 28 in the plates 17 have an arcuate face 31 concentric with the pin 41 and shoulders 23, 24. A balance weight 43 for each plate 17 is pivoted at 42 on the member 11 and has a pin 61 engaging a slot 13 in the plate 17. The cam plates can be positioned in the neutral position shown in Fig. 1, or in two tilted positions in which either a face 21 or 22 abuts a face 38 on the member 11. A nose 56 of a pawl 55 on the member 11 engages the face 22 or notches 57, 58 in the plate 17 to hold the latter in its adjusted position. Only one plate 17 can be tilted about the pin 41 at a time, the other plates 17 being locked in the neutral position by means of balls and cylindrical plugs 47 ... 53, Fig. 4, in a bore in the member 11 and holes in the plates 17. In the operating position, the block 11 is held by the springs 33 spaced from the base 6, the change levers 64, 66 being held by the engagement of the pins 29, 30, with the faces of the slots 27, 28. To preselect on new gear ratio, one electromagnet 69 or 70 is energized to project a pusher 20. To effect the gear change, the electromagnet 7, 8 is energized to pull the block 11 towards the base 6. During this movement, the arcuate faces 31 engage the pins 29, 30 and all the change levers 64, 65, 66 are moved to the neutral position. The plates 17 then abut the pushers 20 and one of them is thus moved into a tilted position. At the end of the stroke of the block 11, the pawls 55 engage the base 6 and are thus disengaged from the plates 17. The electromagnet 7, 8 is then de-energized and the springs 33 return the block to its operating position, the shoulders 23, 24 on the plates 17 engaging the pins 29, 30 to move the levers 64, 65, 66. During this movement, the pawls 55 re-engage the plates 17 and the energized electromagnet 69 or 70 is de-energized. The electromagnets 69, 70, 7, 8 may be replaced by other means such as fluid-pressure servomotors.

Abstract: 731,364. Electroluminescence. SYLVANIA ELECTRIC PRODUCTS, Inc. June 9, 1952 [June 8, 1951], No. 14498/52. Class 39 (1). An electroluminescent material comprising zinc sulphide activated by copper and lead, the lead content being 0.01 per cent or less by weight of the zinc sulphide, is prepared by firing in a stream of inert gas which removes the hydrogen sulphide evolved. There may be a preheating step, also carried out in an inert atmosphere and the starting materials may be in a fluffy condition produced by hammer-milling. The heating takes place in a silica tube, with one end closed by an air lock, and nitrogen, argon, neon or other inert gas is passed over the starting materials which are in silica trays moving through the tube. ZnS (19 mols.), ZnO (1.0 mol.), CuO (0.02 mol.), and PbC0 3  (0.08 mol.), or equivalent compounds, are mixed together initially, much of the lead being lost in the firing process. The zinc sulphide should contain 3.15 per cent zinc chloride, and the luminescence varies from green to blue. The fired material is washed with acetic acid, ammonium acetate, &c., to remove free zinc oxide, dried, mixed with cold pressed castor oil and mounted between electrodes to form an electroluminescent lamp. Specifications 571,690 and 731,345 are referred to.
